This is Posky dreaming of a White Christmas, or what is more probable, a large tin of tuna with prawns on the side. To be honest, I would have preferred him to have chosen a different colour tinsel to curl up with, purple or blue would have looked great against his fur... I know, I know... I'll shut up now.
Processing - What I did... Added copies of the background layer with screen blending mode (played around with the opacity) and a bit of gaussian blur
